Add more calendars.

[avhz]

This involves:

1: Adding a new Market enum variant in calendar.rs

Add either:

• A new country (e.g. Australia).
• Or an MIC code (e.g. XASX) if for a specific exchange.

pub enum Market {
    /// Null calendar.
    None,
    /// Weekend-only calendar.
    Weekends,

    /// Argentina national calendar.
    Argentina,
    /// Australia national calendar.
    Australia,
    ...
}

2: Implement the appropriate is_holiday_impl_* function

Add a new is_holiday_impl_* function in the appropriate file under countries/.

pub(crate) fn is_holiday_impl_australia(date: Date) -> bool {
    let (y, m, d, wd, yd, em) = unpack_date(date, false);

    if
    // New Year's Day (possibly moved to Monday)
    ((d == 1 || ((d == 2 || d == 3) && wd == Weekday::Monday)) && m == Month::January)
            // Australia Day, January 26th (possibly moved to Monday)
            || ((d == 26 || ((d == 27 || d == 28) && wd == Weekday::Monday)) && m == Month::January)
            ...
            // National Day of Mourning for Her Majesty, September 22 (only 2022)
            || (d == 22 && m == Month::September && y == 2022)
    {
        return true;
    }

    false
}

• Argentina
• Australia
• Austria
• Botswana
• Brazil
• Canada

[avhz]

Sure :) take a look at what is already implemented for an idea of what needs to be done.

Thanks for your interest !

Hi, I'm not getting that error. Looks like a problem with the plotters crate.

Is your Rust up-to-date? Try rustup update and re-compile and let me know what happens.

Edit: probably also worth running cargo clean after updating Rust.

Hi thanks @avhz I'm able to build now but how to run this locally getting this.

dakshdagariya@Dakshs-MacBook-Air RustQuant % cargo run            
error: a bin target must be available for `cargo run`

[avhz]

RustQuant is a library, not a binary. So you can't run it.

You may find the Rust book helpful: https://doc.rust-lang.org/book/

I believe there's a chapter about libraries and binaries.

okay thanks a lot.
